In this example, the goal is to pass audio from the left and right auxiliary inputs, into the ADC,
from the ADC into the DAC, and then output to the headphones. This is accomplished by the
following three steps:
Choose: "L/R AUXIN => L/R AuxBstGain => L/RADC => L/RDAC => M Mixer =>
Select for the output: Headphone
Push the "Load Settings" button and verify all three Status Indicators change to Green
At this point, any line level audio input attached to the Aux inputs should be audible in a
headphone attached to the headphone jack. A suitable line level audio source would be the
output from a CD-audio player or other media player device.

Path View Control Panel
This panel shows in a graphical form the internal structure of the device being tested as it related
to the available input, output, and control pins on the device. This is a highly interactive panel,
and most of the features and controls are "clickable." This means that on the GUI screen you can
simply click on a functional block or path and change its settings. You can also use this panel to
see some of the settings that are currently in use.
